The Relationship between Multimorbidity and Quality of Life on Acute Myocardial Infaction Patients Undergoing Percutaneous Coronary Intervention in Haji Adam Malik Hospital Medan

Introduction: Acute Myocardial Infarction (AMI) is one of the spectrums of Acute Coronary Syndrome (ACS) with a high mortality rate. Patients with AMI are often accompanied with comorbid factors that worsen the risk and affect the prognosis so that requires post intervention evaluation. Heart related quality of life proved to be useful in evaluating post intervention and comorbidities management strategies, The Quality of life can be measured using a EuroQoL questionnaire based on the EQ-5D score. This study will determine the relationship between multicomorbidities and Quality of Life. Method: This is a cohort retrospective study of AMI patients who underwent Percutaneous Coronary Intervention (PCI) at the HAM Hospital. Data was collected from April 2022 until the sample was fulfilled. Measurements of comorbid were made based on single comorbid and multicomorbid . The quality of life was determined based on the EQ-5D index score. Bivariate analysis was conducted to assess the correlation between the two variables. Then, a multivariate analysis was performed to assess comorbidities as a predictor of quality of life. Result: Total subjects were 80 AMI patients consist of 30 (37.5%) patients with Good Quality of Life (EQ-5D index score = 1) and 50 (62.5%) patients with Poor Quality of Life (EQ-5D index score < 1 ). There are 41 (51.3%) single morbid patients and 39 (48.8%) multi comorbid patients, and Hypertension was the most comorbid in this study (62 (77.5%) patients). Based on multivariate analysis, it was found that the strongest relationship to quality of life was comorbidities ( OR = 19.338). Conclusion: Comorbidities have relationship with quality of life where multicomorbidity can predict impaired quality of life in AMI patients after percutaneous coronary intervention.
